Ergonomics of human-system interaction — Part 171: Software accessibility

Edition date: 2025-12-05
In Force
Available languages: English, French
Summary:

This document specifies requirements and gives guidelines for designing accessible software for people with the widest range of physical, sensory and cognitive abilities, including those who are temporarily or situationally disabled, and the elderly. It addresses software considerations for accessibility that complement general design for usability as addressed by parts of the ISO 9241 series, especially ISO 9241-11 and ISO 9241-210.

This document is applicable to the accessibility of interactive systems. It addresses a wide range of software (e.g. home, mobile, office, web, learning support and library systems). It promotes the increased usability of systems for a wider range of users in the widest range of contexts of use.

This document does not apply to the behaviour of, or requirements for, assistive technologies (including assistive software), but it does address the use of assistive technologies as an integrated component of interactive systems.

It is intended for use by those responsible for the specification, design, development, evaluation and procurement of software platforms and software applications.



Le présent document fournit des exigences et des lignes directrices liées à la conception de logiciels accessibles pour les personnes présentant le plus large éventail possible de capacités physiques, sensorielles et cognitives, y compris les personnes présentant des déficiences temporaires ou situationnelles, et les personnes âgées. Le présent document traite des aspects logiciels en matière d’accessibilité, qui complètent la conception générale relative à l’utilisabilité couverte par les parties de la série ISO 9241, et plus particulièrement l’ISO 9241-11 et l’ISO 9241-210.

Le présent document est applicable à l’accessibilité des systèmes interactifs. Il couvre une gamme étendue de logiciels (par exemple les logiciels utilisés au travail, à la maison, sur des appareils mobiles ou encore en ligne, l’aide à l’apprentissage et les gestionnaires de documents). Il contribue à l’amélioration de l’utilisabilité des systèmes pour une plus grande diversité d’utilisateurs dans les contextes d’utilisation les plus divers.

Le présent document ne s’applique pas au comportement ou aux exigences en matière de technologies d’aide (y compris les logiciels d’assistance), mais il traite de l’utilisation des technologies d’aide en tant que composant intégré aux systèmes interactifs.

Il est destiné aux responsables de la spécification, de la conception, du développement, de l’évaluation et de l’achat de plateformes logicielles et d’applications logicielles.
